Description

Die vorliegende Erfindung betrifft eine Absaugpumpe für medizinische Zwecke, insbesondere Sekretabsaugpumpe, mit einem Auffangbehälter für abzusaugendes Material, einem Ventilblock zur wechselweisen Verbindung des Pumpenraumes über entsprechende Ventile mit dem Auffangbehälter zwecks Aufbau eines Vakuums in letzterem bzw. mit einer Ausblasleitung, je nach der Bewegungsrichtung eines Membranpumpenstössels, und einer Antriebseinheit des Membranpumpenstössels.The present invention relates to a suction pump for medical purposes, in particular Sekretabsaugpumpe, with a collecting container for material to be sucked, a valve block for alternately connecting the pump chamber via corresponding valves with the collecting container for the purpose of building a vacuum in the latter or with a Ausblasleitung, depending on the direction of movement Diaphragm pump plunger, and a drive unit of the diaphragm pump plunger.

Die heute bekannten Absaugpumpen dieser Art haben den Nachteil, dass mit Ausnahme des abnehmbaren Auffangbehälters die Reinigung der übrigen Pumpenteile aufwendig und schwierig ist, da insbesondere grosse Sorgfalt anzuwenden ist, um das Eindringen von Flüssigkeit (Waschflüssigkeit, Sekretreste) in die Antriebseinheit zu vermeiden.The suction pumps of this type known today have the disadvantage that with the exception of the removable collecting container, the cleaning of the other pump parts is complicated and difficult, since in particular great care must be taken to avoid the ingress of liquid (washing liquid, secretions) in the drive unit.

Eine solche Pumpe ist aus der US-A-5419687 bekannt. Dort ist eine Pumpe offenbart mit einem Gehäuse, in welchem Antriebseinheit und Ventilanordnungen vorhanden sind. Ein Auffangbehälter kann lösbar daran angekoppelt werden.Such a pump is known from US-A-5419687. There is a pump disclosed with a housing in which drive unit and valve assemblies are present. A collecting container can be releasably coupled thereto.

Aufgabe der vorliegenden Erfindung war die Schaffung einer Absaugpumpe, welche bei möglichst einfachem Aufbau leicht zusammenbaubar und für Reinigungszwecke wieder ohne besondere Kenntnisse auseinandernehmbar ist (keine Schlauchverbindungen). Die Bedienung soll äusserst einfach sein (ein Knopf Ein/Aus) und der Auffangbehälter nach seiner Entleerung in der Waschmaschine, z.B. Geschirrwaschmaschine waschbar sein. Auch die übrigen Pumpenteile, d.h. Ventilblock und Antriebseinheit, welche dank einer besonderen Ueberlaufkonstruktion des Auffangbehälters keiner Verschmutzung ausgesetzt sind, sollen bei Bedarf ohne Beeinträchtigung von deren Funktionalität, gereinigt werden können.Object of the present invention was to provide a suction pump, which is easy to assemble with the simplest possible structure and again for cleaning purposes without special knowledge can be disassembled (no hose connections). The operation should be extremely simple (a button on / off) and the collecting container after its emptying in the washing machine, eg dishwasher washing machine be. The other pump parts, ie valve block and drive unit, which are not exposed to contamination thanks to a special overflow construction of the collecting container should, if necessary without Impairment of their functionality, can be cleaned.

Diese Aufgabe wird bei einer Absaugpumpe der eingangs definierten Art erfindungsgemäss durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.This object is achieved according to the invention in a suction pump of the type defined by the features of the characterizing part of claim 1.

Vorzugsweise werden dabei die verschiedenen Pumpenteile auf einer gemeinsamen Grundplatte mittels Steck- und/oder Schnappverbindungen lösbar zusammengefügt, angeordnet.Preferably, the various pump parts are on a common base plate by means of plug and / or snap connections releasably assembled, arranged.

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels noch etwas näher erläutert.The invention will be explained in more detail below with reference to an embodiment shown in the drawing.

Es zeigt:

Fig. 1
rein schematisch eine aus drei Hauptteilen zu bildende Absaugpumpe;
Fig. 2
eine aus den drei Hauptteilen gemäss Fig. 1 zusammengesetzte Absaugpumpe; und
Fig. 3
einen Längsschnitt durch die Absaugpumpe nach Fig. 2 in etwas vergrössertem Massstab.
It shows:
Fig. 1
purely schematically a to be formed from three main parts suction pump;
Fig. 2
a suction pump composed of the three main parts according to FIG. 1; and
Fig. 3
a longitudinal section through the suction pump of FIG. 2 in a somewhat enlarged scale.

Figur 1 der Zeichnung zeigt die drei Hauptteile der Absaugpumpe, nämlich das Hauptgehäuse 1 mit eingebautem Motor, Pumpenantrieb und gegebenenfalls einem Akku (diese Einbauteile sind in Fig. 3 dargestellt), welches auf eine Bodenplatte 2 angesteckt ist, wobei am Hauptgehäuse noch die Membran 3 eines Membranpumpenstössels (s. Fig. 3), der Hauptschalter 4 (Ein/Aus) sowie ein Stromanschluss 5 gezeigt sind, ferner ein Ventilblock 6 mit Ueberlaufkammer (Fig. 3) und Vakuumeinstellknopf 7 (z.B. zwei Stellungen) und schliesslich ein wiederverwendbarer Auffangbehälter 8 mit aufgesetztem Deckel 9.Figure 1 of the drawing shows the three main parts of the suction pump, namely the main housing 1 with built-in motor, pump drive and optionally a battery (these mounting parts are shown in Fig. 3), which is infected to a bottom plate 2, wherein the main housing nor the membrane. 3 3), the main switch 4 (on / off) and a power connection 5 are shown, also a valve block 6 with overflow chamber (FIG. 3) and vacuum adjustment knob 7 (eg two positions) and finally a reusable collection container 8 with attached lid 9.

Die in Figur 1 gezeigten Hauptteile der Absaugpumpe lassen sich leicht zusammenstecken (Steck- und Schnappverbindungen) und selbstverständlich ebenso leicht wieder auseinandernehmen (zu Reinigungszwecken). Der Ventilblock 6 kommt dabei direkt zwischen das Hauptgehäuse 1 und den auswechselbaren Auffangbehälter 8 zu liegen, wie Figur 2 zeigt. Die Hauptteile sind vorzugsweise auf die Bodenplatte 2 aufgesteckt.The main parts of the suction pump shown in Figure 1 can be easily plugged together (plug and snap connections) and of course just as easily disassemble again (for cleaning purposes). The valve block 6 comes to lie directly between the main housing 1 and the interchangeable collecting container 8, as Figure 2 shows. The main parts are preferably attached to the bottom plate 2.

Das erfindungsgemässe Aufbaukonzept ist am besten aus dem Längsschnitt gemäss Figur 3 ersichtlich:The construction concept according to the invention is best seen from the longitudinal section according to FIG. 3:

Im Hauptgehäuse 1 ist ein Elektromotor 10 (z.B. ein 12V-Gleichstrommotor) an einer Platte 11 angeflanscht und dient dem Antrieb des Exzenters 12 (mit zusätzlicher Unwucht 13). Der Exzenter 12 dient dem Antrieb des Pumpenpleuels 14, welcher mit einer Membrane 15 (z.B. umspritzte Membrane) versehen ist und im Betrieb der Erzeugung eines gewünschten Vakuums dient. Ebenfalls im Hauptgehäuse 1, welches auf eine Bodenplatte 2 aufgesteckt ist, ist ein Akku 16 untergebracht. Eine Stromversorgung von aussen erfolgt über die Anschlussbuchse 17 (12V-Gleichstrom zur Speisung des Akku 16 oder zur direkten Speisung des Motors 10). Auf der Oberseite des Gehäuses 1 ist schliesslich ein Druckknopfschalter 18 (Ein/Aus) angeordnet.In the main body 1, an electric motor 10 (e.g., a 12V DC motor) is flanged to a plate 11 and serves to drive the eccentric 12 (with additional unbalance 13). The eccentric 12 serves to drive the Pumpenpleuels 14, which is provided with a membrane 15 (for example, overmolded membrane) and in operation serves to generate a desired vacuum. Also in the main housing 1, which is plugged onto a bottom plate 2, a battery 16 is housed. A power supply from the outside via the connector 17 (12V DC to power the battery 16 or direct power to the motor 10). On the top of the housing 1, a push-button switch 18 (on / off) is finally arranged.

Ebenfalls auf die Grundplatte 2 aufgesteckt befindet sich auf der linken Seite der austauschbare, wiederverwendbare Auffangbehälter 8 für abzusaugendes Material (z.B. Sekret) mit Behälterdeckel 9. Das durch im Behälter 8 erzeugtes Vakuum abzusaugende Material tritt über eine am Stutzen 19 anbringbare Schlauchleitung (nicht dargestellt) in den Behälter 8 ein.Also plugged onto the base plate 2 is located on the left side of the exchangeable, reusable container 8 to be sucked material (eg secretions) with container lid 9. The generated by the vacuum generated in the container 8 material occurs via an attachable to the nozzle 19 hose (not shown) in the container 8 a.

Zwischen Auffangbehälter 8 und Hauptgehäuse 1 ist als dritter separater Hauptteil ein Ventilblock 6 eingesetzt, wobei dieser durch geeignete Verbindungen mit dem Behälter 8 und dem Gehäuse 1 lösbar gekuppelt ist. Da zwischen Ventilblock 6 und dem im Hauptgehäuse 1 untergebrachten Membranpumpenstössel 14 mit an seinem vorderen Ende angeordneter Membran 15 der eigentliche Pumpenraum 20 liegt, ist dieser Raum mit einer Einrichtung zur Einstellung des gewünschten Vakuums (Vakuumeinstellknopf 21 mit z.B. zwei unterschiedlichen Stellungen) verbunden.Between collecting container 8 and main housing 1, a valve block 6 is used as the third separate main part, wherein this is releasably coupled by suitable connections with the container 8 and the housing 1. Since the actual pump chamber 20 is located between the valve block 6 and the diaphragm pump plunger 14 accommodated in the main housing 1 with the diaphragm 15 arranged at its front end, this space is connected to a device for setting the desired vacuum (vacuum adjustment knob 21 with eg two different positions).

In einer Wand 22 des Ventilblocks 6 sind selbsttätig wirkende Ventile 23 bzw. 24 angeordnet: Bei sich in Richtung R bewegendem Pleuel 14 bzw. Membrane 15 entsteht Unterdruck und Luft Wird aus dem Behälter 8 über das sich öffnende Ventil 23 gesaugt (zwecks Erzeugung des Vakuums im Auffangbehälter). Bei der Stossbewegung des Pleuels 14 bzw. der Membran 15 in Richtung L schliesst das Ventil 23 und die in den Pumpenraum 20 angesaugte Luft wird über das sich öffnende Ventil 24 ausgestossen, dies in einen mittels eines Deckels 25 geschlossenen Raum 26, welcher über freie Kanäle zwischen den miteinander gekuppelten Pumpenteilen mit der Umgebung verbunden ist (Aus).In a wall 22 of the valve block 6, self-acting valves 23 and 24 are arranged: When moving in the direction of R connecting rod 14 and diaphragm 15, negative pressure and air is drawn from the container 8 via the opening valve 23 (for the purpose of generating the vacuum in the collection container). In the impact movement of the connecting rod 14 and the membrane 15 in the direction L, the valve 23 closes and the air sucked into the pump chamber 20 is expelled via the opening valve 24, this in a closed space 26 by means of a lid 26, which via free channels between the coupled pump parts with the environment is connected (off).

Die Verbindung zwischen Auffangbehälter 8 und Ventilblock 6 erfolgt über einen hochgelegenen Stutzen 27, welcher notfalls auch einen Ueberlauf für den Behälter 8 bildet. Dank der besonderen Konstruktion würde eventuell in den Ventilblock 6 eindringende Flüssigkeit die Antriebseinheit der Pumpe nicht beeinträchtigen.The connection between the collecting container 8 and the valve block 6 via a high-lying nozzle 27, which forms an overflow for the container 8, if necessary. Thanks to the special design, any liquid entering the valve block 6 would not adversely affect the drive unit of the pump.

Die einzelnen Pumpenteile 1, 6 und 8 können auf einfachste Weise zusammengebaut und demontiert werden, was insbesondere deren Reinigung vereinfacht und problemlos gestaltet (Auffangbehälter 8 und Ventilblock können in der Geschirrwaschmaschine gereinigt werden).The individual pump parts 1, 6 and 8 can be assembled and disassembled in the simplest way, which in particular simplifies their cleaning and makes them problem-free (collecting container 8 and valve block can be cleaned in the dishwashing machine).
